Zinc, antioxidant enzymes in preeclampsia, and association with newborn outcome.

Background: The etiology of preeclampsia (PE) may be associated with the increased of production of reactive species and decreased antioxidant activity of enzymes. Inadequate intake of Zn can affect gestational health due to its biological functions, such as its role in the antioxidant defense system. The study aimed to assess the nutritional status of Zn and antioxidant enzymes in postpartum women and its correlation with neonatal outcomes.

Relationship between zinc-related nutritional status and the progression of multiple sclerosis.

Background: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system.

Objective: To investigate plasma and erythrocyte zinc status and its relationship to MS.

Methods: Cross-sectional study, including 98 participants, distributed in groups: case (MS, n = 49), diagnosed with MS and control (n = 49), matched by age and sex with the case group.
